The conclusion (generally improved UX) sounds a bit dubious: bloat (including bloated graphics and splash screens, as mentioned there) seems to increase, not to decrease with time. Unfortunately the linked report doesn't explain how it is estimated (beyond hinting that ROI for UX work is taken into account), and the full report (which possibly explains it) is paywalled. It's an interesting topic, but the linked document is not very informative.
